Factory for buffer_writer.
The buffer must live longer than the writer. Note that there is no synchronization. Never open two writers for the same buffer in different threads, or access the buffer from any other thread while there is a writer.

Creates a writer.
The pool must live longer than the returned writer.
Offsetable writers can be opened at any position. If the writer is not seekable, pass an offset of 0 or open will fail.
Implements writer_factory.
